Connecting BenQ EW3270U monitor with keyboard

Hey guys so this monitor does not have a usb type A port , if I wanted to connect my 2017 MacBook Pro to this via the usb c cable they provided but how do I connect the keyboard and mouse (sorry if this is a dumb question) . Do I need a cheap usb data hub and plug the usb transmitter to my MacBook Pro via the dongle or should I purchase a bluetooth keyboard and connect it to my MacBook Pro dongle . Will both of these options make the keyboard and mouse functional on the external monitor ? thanks
